Claw Vacuum Pump - KVC

Benefits of Claw Pumps

Reliable and Efficient 

The design of the KVC Series allows for dry compression, meaning no oil or sealing fluid is needed in the compression chamber. This also provides much less wear in the operation. The KVC design optimizes airflow for efficient air cooling. Along with the use of our premium motors, the Kinney design greatly reduces energy consumption and lowers life cycle costs. 

Compact Design and Low Noise Levels 

The compact design of our claw pumps allows for the most efficient use of installation space and provides easy access to all components of the machine, making it easy to inspect and service. The KVC claw pumps can perform at market-leading sound levels, down to 76 dB(A) during operation. 

Claw Rotors 

Our claw-shaped rotors are designed for contactless operation and are expertly designed for the tightest fitting tolerances which provides the highest efficiency in claw compression. None of the internal components make contact, extending the service interval and keeps the pump running longer.  

KVC Claw Features

• NEMA Premium Motor: High-Efficiency NEMA framed motors included and are compatible with Variable Speed Drives.
• Oil-Free Compression: No contaminants released into the discharge air or process. Providing peace of mind and worry-free maintenance.
• Air Cooled: Pump Cooling Fan linked to the drive motor, as well as vent cover openings to keep the unit cool.
• Fully Synchronized Gears: These gears are synchronized to ensure maximum efficiency in rotor movement. The gearbox is lubricated by Kinney KV-150 premium gear lubricant.
• Lifting Eyebolt: Lifting eyebolt for easy transport and placement. The pumping unit can be lifted and removed from the pump assembly frame and easily repaired during service intervals.
• Sealing System: Viton shaft seal and two labyrinth piston O-rings with atmospheric venting so the shaft seal does not become pressurized.
• Small Footprint: Unique stacked design enables a reduction of required floor space.
• Contactless Operation: Ensures minimal wear of parts within the pumping chamber, reducing maintenance downtime.
• Ultimate Vacuum Down to 27"Hg: Ultimate Vacuum down to 27”Hg / 75 Torr to support your application.
• Low Maintenance: Service/Maintenance intervals up to 20,000 hrs. This leads to low cost of ownership and nearly a “set & forget” product.
• High Efficiency: Top of class CFM/HP efficiency and low power consumption due to our overall rotor and cylinder designs.
• Horizontal Shaft: Optimized lubrication, better heat extraction, dissipation, and extended life of gears, bearings, and seals.
• Low Noise: Integrated internal discharge silencer offers some of the lowest sound levels with this technology and combined with the Kinney base and enclosure design features, can achieve sound levels as low as 76 dB(A).
• Extreme Duty: XD models with coated internals and  flush ports for ease of cleaning to prevent internal process build-up in demanding applications.
